IMPROVEMENT IN ,VAPOR-BURNERS.

' Specification forming part of Letters Patent No. 136,02lydatedFebruary 18, 1873.

To all whom-it may concern:

Be it known that we, JOSEPH BENSON and ALBERT H. W ATKINS, both ofBoston, in the county of Snfl'olk and State of Massachusetts, haveinvented certain new and useful Improvements in Vapor-Burners; and thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawing.

This invention, as well as others heretofore made and patented invapor-burners, has for its object to produce a safe, cheap, clear, andbrilliant light from benzine, gasoline, naphtha, and other products ofpetroleum, or of substances which, to burn, are vaporized in theirpassage to the burner-tip. The invention relates particularly to thatclass of vaporburners in which is employed a supplementary jet to assistthe generation of vapors from the illuminating medium. The inventionconsists of a certain combination of parts, the construction of whichbeing hereinafter specified.

In the accompanying plate of drawing, the present invention is.illustrated, Figure 1 being a side elevation of a burner constructedaccording to the first, third, and fourth parts thereof; Fig. 2, acentral vertical section of Fig. 1; Figs. 3 and 4, sectional views inplanes of lines w 00 and 'y respectively, of Fig. 1;

a Fig. 5, a central vertical section and side elevation in part, showingsecond part of this invention.

A in the drawing represents the tubular body of the burner. This bodyAat one end has aburner-tip, B, and at its other end is aperture, d, atits uppertend it communicates with the chamber proper of burner-tube A,and by an aperture, f, at its lower end it opens to the outside oftheburner-tube. This internal chamber 0, with its communicatingapertures, is very plainly illustrated by Fig.

2, and in part by Fig. 3, of the drawing; E, the couplin gformin g thejoint orconnection between burner-tube A and feed-tube F. This coupling,in fact, is part and parcel of the feedpipe F, the two being firmlyscrewed together, forming a continuous connection with burnertube. Thecoupling E has a socket, G, suitable for the reception and hold of theclosed end to burner-tube A, and its communicating passage 9 is in lineto open to the pin-hole a of the burner-tube A. .H, a vertical wing orplate, made of one and the same piece with the coupling E. This wing H,when the coupling, feed=tube, and burner-tube are secured together, isbetween the burner and feed tubes, a short distance from theburner-tube, and projects abovethe' plane of aperture f, tosupplementary chamber 0. I, a bridge-plate, connecting wing H to thecoupling E, near Where the burner-tube enters it; and J,cylindricalshaped hood, made of metal in a sheet or other suitable form.This hood J is secured to a sleeve, K K, and by this sleeve'is locatedin the feed-pipe F, so as tosurround the wing H, making a chamber, L,about the wing back of it, and between it and the burner-tube. Thehood-sleeve K is to tightly fit the feed-tube, and the edges f of thehood J are made with a shoulder, g 9 to sit over and upon the cross-armh of the coupling E, for keeping the hood in its upright position, andfrom turning on feed-tube. The feed-tube Fis filled with wickin g orfibrous matter, and the wing H is open through its center, making twoarms or tines, l l, as'shown. M, asleeve, surrounding outside ofburner-tube. This sleeve is made of a globular'shape, and forms achamber, N, around the outside of burner-tube, that, by one or moreapertures, m, is in communica tion with the chamber of burner-tube, and,by one or more apertures, n, at its lower end, open to the outside ofburner-tube, the-apertures a beingwithin the height of the wing H. 0,air-- passes, and thus completely surrounds the wing, and heats the sameto a high degree,

communicating or conducting the heat, as is obvious, directly to thefeed-pipe F, byand through the connection of parts described.

The hood J protects the supplementary flame from being extinguished bythe external air or gusts of wind, guards the win g against being cooledoff, and most completely retains the heat of wing for being conducted tothe feed-pipe. Heat from the hood is also conducted to the feed-pipethrough its sleeve-connection therewith.

Under our invention, as the heating-wing is located at the bottom of theburner-tube and in the closest proximity to the tube which feeds theilluminatin g-liquid, the most effective results in generating thenecessary gas, and in the economy and retention of heat, are-obtained,rendering'the burners most serviceable for street and other outdoorplaces.

The operation of the burner-shown in Fig. 5 is substantially the same asthat above de scribed.

To clean the pin-hole aforesaid, remove the burner-tube, when it is freefor being operated Witnesses: V
